Abstract
The present invention relates to quaternary ammonium disinfecting cleaning compositions comprising a quaternary ammonium compound, an alkyl a polyglycoside with a CMC greater than 1000 ppm and a chelant. Beneficially, the compositions provide residual sanitizing efficacy without diminished performance and without scale formation when diluted with hard water. The compositions are suitable for inactivating and/or reducing infectious agents, particularly Norovirus, Adenovirus, and Polyomavirus.
